微酸性有机肥用量对滩涂土壤理化性状及水稻产量的影响

Effects of acidulous organic fertilizer rates on both beach soil physicochemical properties and rice yield

在奉贤地区新围垦的滩涂盐碱地上使用微酸性有机肥,对水稻品种‘秀水123'进行了田间栽培试验。结果表明:使用微酸性有机肥45 t/hm^2,土壤理化性状改良效果最佳,使用微酸性有机肥30—45 t/hm^2,能明显促进水稻分蘖,提高水稻单产14.0%—21.4%。

Field experiments with rice cultivar Xiushui 123＇ were carried out in newly enclosed tideland of Fengxian District by using acidulous organic fertilizer.The results showed that applying acidulous organic fertilizer at 45 t/hm^2 could have the best improving effect on the soil physicochemical properties,and applying acidulous organic fertilizer at 30—45 t/hm^2 could significantly promote rice tillering and increase per unit area rice yield by 14.0%—21.4%.
